This invention relates to cooking appliances for use in domestic and commercial kitchens. The invention relates particularly to electric grills that can be used to cook food in a way that removes fat from the food that is cooked. In particular the invention relates to a vertical electric grill.
Obesity together with heart disease has been linked to high consumption of saturated fats and cholesterol found in most meat products. The American Heart Association (“AHA”) has recommended that individuals should, in order to reduce the risk of heart disease and cancer, reduce their daily intake of saturated fats and cholesterol.
Grills in which the radiant cooking elements and grilling space have been arranged vertically are particularly well adapted to remove fats from meat that is being cooked. As the food is suspended between the cooking elements gravity and pressure of a holding clasp act on liquefied fats and oils such that they drip out of and away from the food being cooked. Vertical grills have been recommended by heart physicians as a suitable device to help patients and the public reduce their intake of saturated fats that would otherwise be ingested with conventionally cooked meats. The vertical radiant heat grilling configuration was much favoured by the public as a real grill over ‘grilling’ on or frying on flat metal, Teflon or other fire resistant surfaces.
However, there were problems associated with prior art vertical grills. The prior art vertical grill used an internal drip tray to retain fats and oils that drip down from the food being grilled between two radiant cooking elements. Unfortunately, the prior art vertical grill with an internal drip tray is prone to fire flare-ups and smoke.
As a result if the internal drip tray is not cleaned thoroughly before each use to ensure there are no combustible fats or solids present in the tray, there is a good chance that the contents of the tray will combust. Further, users were also recommended to add a small quantity of cold water to the internal drip tray to reduce the volatility of the liquefied fats and oils that accumulated in the tray.
Because the drip tray was internal to the device some people were unaware of the requirement to clean out the drip tray and/or to add water and as a result the device would sometimes catch fire.
As a result of fire risk, some prior art vertical grill designs employed an internal drip tray that features a fire suppressing perforated metal cover. However this design had its drawbacks. First, the perforated cover actually makes it more likely that a user of the device will forget to empty the contents of the drip tray as the retained oils and fats will be mostly obscured by the internal drip tray cover. In such a case where the internal drip tray is hidden from view within the body of the vertical grill, dangerous reserves of retained fats and oils could easily go unobserved. Further, the use of a perforated metal fire suppressing shield resulted in solid spoils and embers from above, coming to rest on the protective fire shield. These solids sometimes blocked the perforations resulting in an accumulation of fats and oils on its surface which, along with the solids themselves, can often result in smouldering embers and ignited fats entering into the internal cavities of the device, and/or cause the fats in the drip tray to ignite despite the presence of the fire suppressing shield. It is a common complaint by users of the vertical grill that a blocked or inappropriately prepared internal drip tray can permit smouldering embers to activate kitchen fire alarms.
It is an object of the present invention to improve on the design of prior art vertical grills and/or to substantially ameliorate some of the shortcomings of the prior art vertical grills.
A first aspect of the invention comprises an electric grill for cooking food items, wherein the electric grill is comprised of a body containing at least one vertical grilling area disposed between at least two sources of radiant heat energy, and wherein the body is adapted to direct fats and breakaway solids generated during the cooking of the food away from the cooking element down through the body of the electric grill and out into an external receptacle.

Referring to
The prior art vertical grill 10 had the major disadvantage of collecting splattered fat and bits of food directly under the cooking area of the grill, either in the internal drip tray 20, or just above the perforated cover 26. These areas are subject to high radiant heat and high temperatures and as a result, the contents of the internal drip tray 20 or the food and fat that may sit on the perforated cover 26, may catch fire or generate large amounts of smoke.
A potential solution provided herein to ameliorate the above stated problem involves providing a electric grill in which the fats and breakaway solids are channeled to a receptacle or drip tray that sits outside of the body of the grill, away from high heats.
The first embodiment of the invention is shown in
A hooded external drip tray 34 is shown in
Depicted in
The flat slide 44 is inserted between base element 48 and top guides 46 and comes to rest such that its lower edge 54 sits slightly higher than the top edge of external drip tray 32 so that food and fats that fall on the flat slide 44 fall into the external drip tray 32 where they are not subjected to high heat and accordingly will not catch fire.
A third embodiment depicted in
A fourth embodiment depicted in
A fifth aspect of the invention depicted in
In a sixth embodiment of the invention (not shown), the single flat slide which is installed at an angle is replaced with an inverted V shape slide which is centered under the removable reflector/splatter shield 62 such that each of the vertical grilling areas 64 sits over an angled portion of the inverted V slide, wherein the angled portion delivers splattered fats and breakaway solids to two external drip trays which are located at either side of the vertical grill. In this embodiment the inverted V slide is formed in one piece and is inserted and removed via one of the short sides via a V shaped slot formed in the short sides of the grill. Alternatively, the inverted V slide may be formed by introducing two flat slides into the body of the vertical grill, through one or more sides, including the ends and the longer front or back sides. In this embodiment top guides and base elements may be used to guide the individual flat slides into place where they form the inverted V structure when both are inserted.
All of the embodiments described feature a power switch 18 and at least one separate timer knob 42. The heat emitted by the elements 24 may be controlled with a rheostat or other similar component. The second, third, fourth and fifth embodiments also feature space 50 for a cord storage area if desired, through the installation of a door, aperture, recess or compartment (not shown).
